A ray-tracing algorithm for interactive visualization of very large and structurally complicated scenes presented in the constructive solid geometry (CSG) form is suggested. The algorithm is capable of visualizing such scenes in real time by using a graphic processor. As primitives, classical shapes and objects represented in an analytical form (in(More)
The objective of this paper is to adapt photon mapping for real-time simulation of caustics. High-performance algorithm adapted for the GPU and implemented on the basis of cross-platform OpenGL and OpenCL APIs is proposed. For effective rendering of caustics and generation of photon map OpenGL shaders are used. Voxel acceleration structure constructed(More)
A novel GPU-optimized CSG ray-tracing approach is presented that is fast and accurate, and allows achieving real-time frame rates at full-screen resolutions. It has no limitations on the maximum number of primitives, and produces final image in a single pass. We propose an efficient procedure to transform an input CSG tree into equivalent spatially coherent(More)
